Guidelines for choosing indexes A few simple guidelines to help choose the type of index you need for your application: If you need to perform only point lookups, meaning you need to retrieve only the rows corresponding to a single index key value, use a hash index. Nonclustered indexes support retrieving ranges of values, and also support retrieving the table rows in the order that was specified when the index was created
However, if you use the integer values for partitioning and you want to partition based on date, then your application must ensure that records for a given week, month, quarter or year (depending on your implementation) must fall into certain ranges of integers. Fact Internet Sales table only contains about 60000 records, but for the sake of example, populate it with 60 million sample records to resemble a real life data warehousing scenario

Covered compound indexes are normally the most efficient way for indexing since they comprehensively cover all table columns that exists within your T-SQL queries and thus can replace index scans with index seeks.

SQL Server Forums - if exists drop index
what i'm trying to do is if exists (indices) drop...perform updateadd index.how would i go about writing out the drop indices if exists? also would you recommend this to be the best way? theres 1 clustered and about 12 non clustered indexes that i plan to create.look forward to your response. In all of the above examples, any table with that index name will show it as "existing."You need to be sure to include your table name with your index check
If you open the properties window and highlight the top level select of that above plan from SSMS 2005 against SQL 2005 you should see the list of suggested indexes with an impact number
Index and Statistics When retrieving data, SQL Server obviously has to make some decisions as to the best way to get to data and return it to the query requesting it. You can add nonkey columns to the leaf level of the Non-Clustered index to by-pass existing index key limits, 900 bytes and 16 key columns, and execute fully covered, indexed, queries
Less Than Dot - Blog - Creating Mailing Labels in SQL Server Reporting Services
Reply Carol929 says: March 10, 2011 at 10:52 am This set of instructions to create mailing labels was so perfect and on time for me, since I needed to get it done quickly. Are you currently running a report to get your customers mailing information, then using Mail Merge in Microsoft Word to create the labels? Perhaps you are simply exporting the data out of the database
If you want to test this out (and check it on various versions of SQL Server), use this script to setup a test database, a test table and then use dynamic string execution to loop through (until it errors) with creating nonclustered indexes and statistics: IndexMax.sql (853.00 bytes)
You do not need to have a derived column in your view, but if you do, the derived column(s) must have a name or an alias assigned to it to be able to create the view. The properties you can set on the view include (but are not limited to) a description, the schema that owns the view, and whether to bind the view to the schema

SQL SERVER - 2008 - Creating Full Text Catalog and Full Text Search - CodeProject
2) Create a Full-Text Index 3) Populate the Index As the Index is created and populated, you can write the query and use it in searching records on that table which provides better performance
create index abc on table xyz select * from xyz with (index abc) when we run this statement in one transaction the index is not gets created but separately it do.

sql server - Why use the INCLUDE clause when creating an index? - Stack Overflow
So, if you want to cover queries, you can put the search criteria to locate rows into the sorted columns of the index, but then "include" additional, unsorted columns with non-search data. The reason that you give two shakes about this, is that when you run your query, if you don't have the additional columns included (new feature in SQL 2005) the SQL Server has to go to the clustered index to get the additional columns which takes more time, and adds more load to the SQL Server service, the disks, and the memory (buffer cache to be specific) as new data pages are loaded into memory, potentially pushing other more often needed data out of the buffer cache
How to create non-clustered indexes on a SQL Server 2008 database? Preferably without code? - Server Fault
That is, ideally there's a tool within Microsoft SQL Server built into Visual Studio 2010 Professional (NOTE: I DO NOT HAVE ENTERPRISE OR ULTIMATE EDITIONS--THIS MAKES A BIG DIFFERENCE AS TO WHAT I CAN DO WITH THE BUILT-IN SQL MANAGER IN PROFESSIONAL VERSION) to do this--since I don't have any other tool (I just looked, and found that Microsoft SQL Server 2008 does not have what I need--at least on my system--it is apparently a crippled freeware version). I am working from the Server Explorer from inside of Visual Studio 2010, which has a lot of functionality including the ability to generate SQL queries
it Give Result of 28K Searchable Result in Just 4 ms(MYSQL Database).So this criteria is also work with SQL Full Text Search.and i Get same result in same or less then this duration. The problem is that if after adding a pdf and searching it immediately, it does not give the result using full text search, but I can see the row added in the table
CREATING INDEX SQL Server 2008 - Stack Overflow
If you select only the PresidentNumber and one or more of President, YearsInOffice, or RatingPoints columns, and the ElectoralVotes is not null, then your query will get values from the index itself and not have to touch the underlying table. If your table has additional columns and you include one of those in your query then it will have to retrieve values from the table as well as the index
